Registers markup style properties, whether literals or dynamically generated, from the source file so that they can be properly rendered to the requesting client.
Assembly: System.Web (in System.Web.dll)
The predefined cascading style sheet (CSS) attributes of the HTML markup language are registered by calls to the method when the first HtmlTextWriter object is created. Dynamic style attributes can be registered by using the method at other times.
The registration table used by the method is static, so registration of attributes applies to all HtmlTextWriter objects on the host computer.
